Application filed September 13, 1913. Serial No. 789,707.

T all whom it may concern:

Be it known that l, EDWARD H. ELLtsoN,

i a citizen of the lUnited States, residing at Jamestown, in the county of Chautauqua and State of New iLorlt, have invented certain new and useful improvements in Comlmake the compressor adjustable relatively to the drawer and make its final action automatic on the closing of the drawer.

Another object of this invention is to mount the compressor so that it will be p moved to its final compressing position with a strong leverage.

Another object of this invention is to mount the compressor so that it will yield slightly to accommodate itself between the leverage which forces its. position and the contents of the drawer.

Another object of this invention is to mount the compressor so that it will be released by the opening of tlieldrawer and forced to compressing position on the closing of the drawer.

Another object of this invention is to provide in the drawer a slide extending the length of the drawer that is operated on the opening and closing of the drawer, the compressor being fastened inanually'in any position on this slide.

.Another object of this invention is to arrange the drawer and the casing containing it so that the compressor will be operated,

from without the drawer and preferably through lined parts on the casing.

rlhese and other objects of my invention will be illustrated in the drawings, described in the specification and pointed out in the claims at the end thereof.

In the accompanying drawings, Figure 1 is a front elevation of a filing case containing a plurality of filing drawers adapted to in invention. Fig. 2 is avertical'section on-the line QX--QX of Fig. 1. Fig. 3 is a detail perspective view of the .operating cam on the casing containing the drawer. Fig. l is a perspective view of the rear end of the drawer partly broken away. Fig. 5 is a liange 20. Near the rear end detail view of the forward portion of the bottom of the drawer.

ln the accompanying drawings, like reference numerals i'eier to like parts.

ln the drawings, reference numeral 1 indicates the casing having a plurality of drawers 'i2- 2 mounted therein. Each of these drawers is provided with a channel bent in the bottom thereof in which channel the slide 4 is mounted to reciprocate therein. rl`his slide has a cross pin 5 at its rearward end and has the recess 6 in its forward end. Mounted in the channel 3 is the stud 7 with which the recessed end of the slide engages and by which it is held to A place in its forward and back movement. At the rear end of the drawer, the shaft 8 ismounted to oscillate in suitable brackets 9 and 1U. rlhis shaft carries the crank 11 thereon, the lower end of which s slotted at l2 to engage with the pin 5 so that as the shaft S rocks, the slide a lis moved forward and back through the engagement between the crank 11 and the pin 5. Mounted on one end of the shaft S is the crank 13 having the pin 14 in its outer end. Mounted on the casing is the channel 15 which is adapted to receive a similar channel 1G on the drawer by which engagement the drawer is adapted to slide in the channel. rlhese channels are arranged in pairs on each side in the casing is the cam plate 17 having the downwardly inclined iange 1S, the upwardly inclined iange 19 and the vertical of the cam plate 17 is pivot-ally mountedat 21 the cam lever This cam lever is provided with the pin 23 thereon which pin is connected by the spring 221 to pin 25 mounted on the upper end of the cam plate 17.

The 'operation of the parts will now be understood as follows: When the drawer is closed, the pin 111 will engage the cam lever 22 which is held up by the spring 24C. As the pin 1li moves back along its engagement with the lever 22, it forces the arm 125 upwardly into the position shown in the upper part of Fig. 2, causing the slide 4; to move forward, and if the slide 4 encounters resistance, 'it limits the upward movementof the crank 13 and causes the lever 22 to e vlad, to shde hmsmm :L
